Abstract:A new method for synthesizing 2,6-dichloroadenosine was reported in the paper. The starting material 2,6-dichloropurine was condensed with 1,2,3,5-tetraacetylribofuranose at 130℃ for 18 minutes to form 2',3',5'-triacetyl-2,6-dichloroadenosine,which was deprotected in H2SO4-CH3OH at 0~5℃ to give the target product 2,6-dichloroadenosine as a white crystalline powder. The yield was 63%,purity(HPLC)≥99.0%,and the melting point of the product was 152~154℃. |
Key words:2,6-dichloroadenosine;2,6-dichloropurine;1,2,3,5-tetraacetylribofuranose |
